GrapeCity.CalcEngine.Functions Namespace / CalcConfidenceFunction Class / Evaluate Method / Evaluate(Object[]) Method

The args contains 3 items: alpha, standard_dev, size.

Alpha is the significance level used to compute the confidence level. The confidence level equals 100*(1 - alpha)%, or in other words, an alpha of 0.05 indicates a 95 percent confidence level.

Standard_dev is the population standard deviation for the data range and is assumed to be known.

Size is the sample size.
